The outgoing House speaker was a late addition to Thursday night's show, joining guests Michael Fassbender, Brie Larson and CeeLo Green.

Outgoing House speaker John Boehner no longer will appear on Thursday's Tonight Show, a rep for the NBC late-night show tells The Hollywood Reporter, after majority leader Kevin McCarthy withdrew his name as a candidate to be Boehner's replacement.

On Wednesday, The Tonight Show announced that Boehner would join Thursday's lineup, which also includes guests Michael Fassbender, Brie Larson and CeeLo Green.

On Thursday, McCarthy surprisingly withdrew from the race to replace Boehner just moments before an election in which McCarthy was likely to be chosen as House speaker. McCarthy was the favorite to replace Boehner, who announced less than two weeks ago that he would resign as speaker on Oct. 30.

After McCarthy's news, Boehner said Thursday that he will stay on as speaker until the House votes to elect his successor.

Boehner was set to be the latest politician to appear on the Jimmy Fallon-hosted Tonight Show, which recently has welcomed presidential candidates Jeb Bush, Chris Christie, Donald Trump, Carly Fiorina and Hillary Clinton.

No further information was available about why Boehner's appearance was canceled or whether it would be rescheduled.
